Abstract (en)

[origin: EP1501192A1] Systems and methods are disclosed for a power-on reset used in low power supply voltage applications (i.e., having a full operating power supply voltage of less than about 2.0 volts). One embodiment of the reset circuit comprises a differential voltage generation circuit and an amplifier circuit. The differential voltage generation circuit is adapted to create two voltages changing at different rates. The amplifier circuit is adapted to amplify a difference between the two voltages. <IMAGE>
